Canada Post also published the abbreviations for provinces and territories [1]

e.g. Whitehorse, YT Toronto, ON Charlottetown PE

For wide roads (at least 3 lanes on each direction) with two directions of traffic, create two one-way roads so that a GPS lock will be made correctly. Note: standard lane width is about 3.5m, typical GPS accuracy is about 10-20m.

Towns, cities villages etc... To save space Just put in the name of the city, example "Toronto" not "City of Toronto", or for smaller places use "Springfield" not "Town of Springfield" or "Village of Springfield"
Also unique to Canada is we don't have state or province fields available to us when editing, please avoid the use of the province after the place. For example don't put in "Springfield, Qc" or "Springfield, On" because it is known to make two towns in the same place, and is almost impossible to eradicate. Many towns have "Springfield" and "Springfield, Qc" in the same area which confuses things which we're trying to avoid.

Quebec Roads:

Autoroutes, or limited access highways, such as the 20/40/55 or any *40 are considered freeways

The big exception to this rule is Autoroute 50 which is still a freeway, even though some small parts of it are not limited access and some are only two lane with no divider.

100 & 200 series highways, for example the 117, the 132 138 148 201 are major highways when compared to 300 series highways and should be in red.

300 series highways such as the 315,321,327, and the 329 are minor highways and should be in yellow.

Ontario Roads:

all 400 series highways are in blue as they are limited access freeways. Also other highways for example the 174 just east of Ottawa are also in blue as they are limited access.

Certain Major highways are two lane but are still in red because they collect the minor highways, and many county roads and we need to distinguish them, examples are the 174 east of Ottawa/Orleans, the 17, the 138, 38 the 7 in eastern Ontario.

County roads will be in yellow as they have higher speed limits them most main roads.
